There were Senate endorsements galore in GOP circles today, with a few of the highest profile conservative Senators coming out in support of candidates locked in tough GOP primaries. Here’s a quick rundown of what happened:

• Texas Solicitor General Ted Cruz picked up an endorsement from Sen. Tom Coburn (R-Okla.). Alluding to one of the most intense rivalries in college football (between the University of Texas and the University of Oklahoma), Coburn wrote in a statement, “Oklahoma and Texas may have our friendly rivalry, but when it comes to fighting for limited government, I’m proud to endorse my neighbor across the Red River.”

• Along with Sen. Ron Johnson (R-Wis.), Coburn also gave his nod to businessman John Brunner, one of three contenders for the GOP nomination in the Missouri Senate race. “John Brunner will be a force for fiscal conservatism in the U.S. Senate, and I am proud to endorse his candidacy,” Coburn said in a statement released by the Brunner campaign. Earlier this year, Sen. Mike Lee (R-Utah) endorsed former state Treasurer Sarah Steelman, another GOP contender hoping to take on vulnerable Sen. Claire McCaskill (D-Mo.) in November.

• Finally, Lee backed Maine Treasurer Bruce Poliquin in the Pine Tree State’s GOP Senate primary. A source in the Poliquin camp told Roll Call that a statement is forthcoming.
